  2. Labor Force Survey in Finland • Telephone interview (CATI) • The sample of 12,000 by month • A random sample of 15 to 74 year-olds Finns • Questions about the whole household are presented in the last (5th) interview • There are five waves in 1,5 years • The response rate is about 70‒75% Kirsti Pohjanpää

  3. The Web Pilot Study of LFS • One aim of the pilot is to find out if there is some mode effect between telephone interview (official LFS) and web data collection (the pilot data) • LFS normal data as a comparison data • data collection at the same time • different data collection mode (telephone – web) • Data collection at October 2013 • There were some split plot tests in the pilot • ESSnet Data Collection forSocial Surveys using Multi Modes Kirsti Pohjanpää

  4. The Web Pilot Study of LFS • Sample size n=8,000 • A random sample of 15 to 74 year-olds • Data collection at October 2013 • Four fixed reference weeks • The questionnaire is coded by Blaise IS • Only in Finnish • Response rate 30%, data n=2,366 • Respondents found the questionnaire quite good Kirsti Pohjanpää

  13. Conclusions • The design, and testing of questionnaire is very important, and has power to the quality of data • The grid form of asking working hours recommended • No (statistical significant) mode effects in main indicators • More studies needed to confirm the best quality of LFS data when mixing data collection modes • Web and mixed mode data collection will be a normal part of statistical process of LFS in future Kirsti Pohjanpää
